Abstract
The utility model discloses a clamping hoop. The clamping hoop comprises a bolt, a hoop seat and a hoop band, wherein the bolt freely rotates on the hoop seat, and the tail portion of the hoop band is fixed together with the lower end of the hoop seat. The clamping hoop is characterized in that the lower end of the hoop seat and the tail portion of the hoop band are mutually fixed in a cold riveting mode. The clamping hoop has the advantages that due to the fact that by adopting the cold riveting mode, stable size of the hoop seat is ensured, deformation will not occur, the force moment index of the machined worm and gear clamping hoop is also steady and small in fluctuation, and the index is easy to control; through the cold machining, reliability reaches 100%. The problems that the index of the worm and gear clamping hoop fluctuates, and the reliability can not reach 100% are completely solved.
Description
Technical field
The utility model belongs to a kind of pipeline connection and uses product scope, relates in particular to a kind of clip by being used in fuel pipe connection use on fuel power.
Background technique
The connection of the pipelines such as the cooling system of existing fuel power, air inlet system and exhaust system, oil-fired system, lubrication system can be used a large amount of clips, and clip generally all is comprised of bolt, band and hoop seat; Screw thread is arranged on bolt, the groove of the protruding injustice of stamped female on band, the angle and distance of groove and the screw thread on bolt coincide, band is processed conglobate worm gear shape, process separately a housing (hoop seat) bolt and band combined, just consist of the clip of a locking, because of bolt shape as worm screw, band is as worm gear, so assembly parts is worm gear clamping hoop.by rotating bolt (worm screw), drive band (worm gear) rotation and complete locking and loosening process, the technical difficulty of this clip is the processing of hoop seat that bolt and band afterbody are combined, normal conditions are hoop seat and the welding of band afterbody, the one, assembling again after welding in advance is good, the 2nd, weld together with band when assembling, the shortcoming that this processing technology is brought is: 1, the index fluctuation is large, the dimensional changes of bringing due to welding deformation, cause the fluctuation of clip chucking moment index, locking torque is not easy to control, 2, welding belongs to special process, be not easy to control, require high to equipment and personnel, can't be avoided by rosin joint and the excessive hidden danger of quality that causes of welding, can produce Accident due to quality, can't accomplish 100% Reliability Assurance to quality of product.Make the field at clip at present, hidden danger of quality how to avoid the welding of worm gear clamping hoop hoop seat to bring is perplexing the clip manufacturing industry always!
The model utility content
The purpose of this utility model just is to provide a kind of clip, and it has the dimensionally stable that guarantees the hoop seat, does not produce distortion, and also constant fluctuation is little for the moment index of processing rear worm wheel worm screw clip, and index is easily controlled; By cold working, reliability reaches 100%.Solve thoroughly index fluctuation and the not thorough problem of reliability of worm gear clamping hoop.
The technical solution of the utility model is: a kind of clip, comprise bolt, hoop seat and band, described bolt rotates freely on the hoop seat, and the band afterbody is fixed together with binding round a lower end, it is characterized in that: described hoop seat lower end and band afterbody fix with the form of cold riveting.The technology of this technological scheme is exactly a bit to guarantee that the hoop seat does not produce any type of distortion with the band means of fixation, guarantees after processing that product each other can larger error, has guaranteed the up-to-standard rate that coordinate and guaranteed product of hoop seat with band.
Further, described hoop seat lower end and the monolateral cold riveting of band afterbody.The technical program is for the ease of the rapidity of cold riveting and reliability, makes easily also simple in structure.
Further, described hoop seat head also is provided with guide head, described guide head is provided with bolt hole, bolt rotates freely at hoop seat guide head, the extension is formed with guide lug on guide head is axial, described guide lug is half packet form parcel bolt, and the advantage of this technological scheme has guaranteed that fully bolt guarantees that in movement process its correct trend prevents from and jump head.
Further, described guide lug has 2, is separately positioned on the both sides of the length direction of bolt.The advantage of the technical program guarantees the conformity of worm screw moving direction in movement process exactly by two guide lug are set, can in use not produce the phenomenon that swings and when falling back bolt drop out from the hoop seat.
Further, head at described bolt also is provided with guiding groove, the corresponding bolt guiding groove of described guide head, described guide head is embedded in the guiding groove of bolt head, its technological merit be exactly make bolt and valve jacket consist of whole, guarantee the correct trend of shell ring when fastening and the safety of the tooth on band, run-off the straight and jump head when preventing that bolt from rotating.
Further, the tooth that described band upper punch presses out when this technological scheme is clamping bolt, screws out the band deviation angle that comes little in the left side of band and over against by bolt head, and is little to the shear action of sebific duct.
Beneficial effect
The beneficial effects of the utility model are to guarantee to bind round dimensionally stable between seat and band by the mode that adopts cold riveting, can not produce distortion, and also constant fluctuation is little for the moment index of the screw thread after processing on bolt and band, and index is easily controlled; By cold working, reliability reaches 100%.Solve thoroughly index fluctuation and the not thorough problem of reliability of bolt and screw.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the structural representation that bolt of the present utility model amplifies.
Embodiment
structural representation of the present utility model as shown in Figure 1, a kind of clip, include hoop seat 2 and band 1, described band has afterbody, described afterbody is fixed together with a hoop seat lower end, the seat lower end of hoop described in the present embodiment and band afterbody fix with the form of cold riveting, and the hoop seat is monolateral cold riveting structure, the corresponding in the axial direction bolt guiding groove of guide head 5 on described hoop seat 2 heads, bolt 3 can rotate freely on guide head, described guide head 5 also is provided with guide lug 4, guide lug 4 is half packet form wrapping portion bolt and plays the guiding fixation, described guide lug has 2, be separately positioned on the both sides of bolt, as shown in Figure 2, also be provided with guiding groove 6 at bolt head, guiding groove coordinates with a hoop seat guide head, be used for making bolt and guide head consist of whole, guarantee the correct trend of band when fastening and the safety of bolt, run-off the straight and jumping head when preventing the bolt installation.
The tooth that the described band upper punch of this structure presses out is in the left side of band and over against by bolt head, and when using clip, the band angular deflection that screws out when tightening clip is little like this, can keep best angle to the locking of sebific duct.
